There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Create a CSVRecordReader to hold customer churn data."

A block of code is set as follows:

File file = new File("Churn_Modelling.csv");
recordReader.initialize(new FileSplit(file)); 

Any command-line input or output is written as follows:

mvn clean install

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "We just need to click on the Model tab on the left-hand sidebar."
